A42MX16-3PQG160I

Overview

The A42MX16-3PQG160I is a Field Programmable Gate Array from the Microchip MX family, housed in a 160-pin PQFP package. It features 608 Logic Elements and approximately 24,000 system gates. The device supports dual-voltage operation with a core supply of 3.3 V and I/O supplies ranging from 4.5 V to 5.5 V. It provides 125 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. This component serves as a high-density programmable logic solution for complex digital designs.

Feature Summary

• Single-chip ASIC alternative capability consolidating multiple discrete logic devices
• Mixed-voltage operation supporting both 3.3V and 5.0V core and I/O configurations
• Deterministic timing with user-controllable pin locking and resource utilization

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interface implementations
• DSP and co-processor function acceleration

Procurement Notes

Verify current availability status as this part may be subject to discontinuation or limited production runs. Confirm RoHS compliance and moisture sensitivity level requirements prior to procurement. Ensure compatibility with existing PCB footprints and reflow profiles for the PQFP-160 package.

Selection Notes

Select this model when requiring high gate density in a QFP form factor without BGA complexity. Compare against A42MX16 variants with different speed grades or package types if thermal or pin count constraints differ. Verify that the 125 I/O count meets interface requirements for the target application.

Part Context

This component belongs to the Actel/Microchip MX FPGA family, designed to replace complex PALS, CPLDs, and standard FPGAs. The A42MX series is known for non-volatile Flash-based technology, eliminating the need for external configuration memory. It bridges the gap between simple PLDs and high-end FPGAs.

Replacement Considerations

Direct substitutes include other A42MX16 speed grades such as A42MX16-1PQG160I or A42MX16-2PQG160I. Package variations like CQFP-172 or TQFP-176 exist within the same logical family but require schematic and layout modifications.
